Upsets came thick and fast in an unpredictable latest round of national Rugby League action.
Premiers Brisbane crashed at Cronulla, red-hot North Queensland allowed Penrith to snap a five-game losing streak, Canberra continued South Sydney's free-fall and the last-placed Sydney Roosters downed the Gold Coast.
Wests Tigers made it four in a row - after impressive wins over big guns Melbourne, the Bulldogs and Cronulla - and moved into fifth on the NRL ladder after scoring four second-half tries to put St George Illawarra away 27-8.
The Roosters survived a try scored from a blatant forward pass to down the 10th-placed Titans 24-18
The Roosters' second win of 2007 wasn't enough to get them off the bottom of the ladder but joining them in the cellar on six points are the Dragons, Broncos and Panthers.
Manly sit alone at the top of the table on 16 points after their 22-12 win over 11th-placed Parramatta on Friday, but could be joined by Melbourne tonight when the Storm host the ninth-placed Bulldogs at Olympic Park.
North Queensland remain outright third on 12 points despite their upset 22-12 loss to Penrith.
The Sharks are fourth on 10 points after their 16-8 comeback win over Brisbane
The sixth-placed New Zealand Warriors slumped to a second straight narrow loss as Newcastle fought back from 18-6 down midway through the second half to clinch a 24-18 win at Energy Australia Stadium.
